My first game was 14th November 1959 (Aston Villa 11 Charlton Athlectic 1 :-) )
I havent kept count of how many games, but have had a season ticket for many, many years at various times in the Holte, Witton Lane, North Stand and now Trinity. Following marriage, kids etc my attendance was poor to middling in the mid 80's to early 90's. My "heyday" in terms of travelling to away matches would have been beginning of 70's through to early 80's - however for the last 10 years the average has probably been 5-8 away per season.
So purely an estimate but reckon with cup, home, away etc somewhere in the region of 1500 - 1750
